Software testing is an investigation conducted to provide stakeholders with information about the quality of the software product or service under test.

Astronomers’ tools

5 years ago, on December 19, 2013, the ESA launched an orbital telescope called Gaia. Learn more about the Gaia mission on the official website of the European Space Agency or in the article by Vitaly Egorov (Billion pixels for a billion stars).

However, few people know what technology the agency chose for storing and processing the data collected by Gaia. Two years before the launch, in 2011, the developers were considering a number of candidates (see “Astrostatistics and Data Mining” by Luis Manuel Sarro, Laurent Eyer, William O’Mullane, Joris De Ridder, pp. 111-112):

Comparing the technologies side-by-side produced the following results (source):

Technology Time
DB2 13min55s
PostgreSQL 8 14min50s
PostgreSQL 9 6min50s
Hadoop 3min37s
Cassandra 3min37s
Caché 2min25s

The first four will probably sound familiar even to schoolchildren. But what is Caché XEP?

Cucumber / Gherkin integration

Are there any BDD testing automation implementations within Mumps/Cache Objects already in existence?

We are looking at using Cucumber for our Java regression test automation and would like to use similar feature file testing with the Cache code.


Looking to use something existing before building it.

Regards,

I needed to know programmatically if last ran failed or not.

After some exploring, here's the code:

ClassMethod isLastTestOk() As %Boolean
{
  set in = ##class(%UnitTest.Result.TestInstance).%OpenId(^UnitTest.Result)
  for i=1:1:in.TestSuites.Count() {
    #dim suite As %UnitTest.Result.TestSuite
    set suite = in.TestSuites.GetAt(i)
    return:suite.Status=0 $$$NO
  }
  quit $$$YES
}

I want to test automatically that HL7 business operation works correctly in error conditions. One is to test CE acknowledgement. I have planned to implement test production which includes business services for different situations (AA, AE, CA, CE, timeout, late response etc).

How should I implement HL7 business service that always returns CE (commit error)? I have tried but it keeps returning "AA".

Continuing on with providing some examples of various storage technologies and their performance profiles, this time we looked at the growing trend of leveraging internal commodity-based server storage, specifically the new HPE Cloudline 3150 Gen10 AMD processor-based single socket servers with two 3.2TB Samsung PM1725a NVMe drives.

Hi,

Interested in testing the Eclipse / Atelier on my Mac with 10.13.6 High Sierra, I installed both and had a go at connecting to my Cache Server. It offers Address & Port and login ID and Password.

No matter what I gave it, it cannot connect, saying Server not found.

The Server is a virtual Server running Windows 12 Server on a dedicated IP address, to which I can connect correctly using Remote Desktop, I can Ping the IP so all looks good, except Eclipse cannot find it.

Any hints would be appreciated.

Thanks,

Rosti.

We have one user that is having issues in Ensemble via browser. The two issues she reported are:

- If she opens a DTL, she has to Save or Compile the DTL before she is able to edit anything in the Actions tab. Typically, you can simply open the DTL, click on a line, and edit the Actions.

- If she opens the Tools tab and clicks the Test button, she does not get a response and it eventually times out on her. Typically, clicking the Test button will open a new window where you can paste a message to test your DTL with.

How is your code health

As a developer, usually I'm concerned about how my code health is, and how the other coders code can affect to my own work. And I'm quite sure most of us feel very similar.

In our company we use a Static Code Analysis tool to analyze code for different languages to ensure we are writing high quality and easily maintainable code by following a few best practices in terms of code structure and content. And the question was: why should be different for Caché ObjectScript language?

Often InterSystems technology architect team is asked about recommended storage arrays or storage technologies. To provide this information to a wider audience as reference, a new series is started to provide some of the results we have encountered with various storage technologies. As a general recommendation, all-flash storage is highly recommended with all InterSystems products to provide the lowest latency and predictable IOPS capabilities.

The first in the series was the most recently tested Netapp AFF A300 storage array. This is middle-tier type storage array with several higher models above it. This specific A300 model is capable of supporting a minimal configuration of only a few drives to hundreds of drives per HA pair, and also capable of being clustered with multiple controller pairs for tens of PB's of disk capacity and hundreds of thousands of IOPS or higher.

creating a test server

hi, new here, and new to cache and deepsee.

i've been trying to setup a copy of our production server so we can use it for testing/development.

i did a full backup. moved it to the new server. ran the DBREST command. got it to restore but seems like permissions get all messed up. and it just generates a bunch of errors.

is there an easier/better way of doing this?

Hello,

I have a property which I need to move from one class definition to another as follows:

Old definition:

Class SCHED.SchedEntry
{
  
  Property Experiment as %String;

  Property ScanSlot as list of TracerEntry;

}

Class SCHED.TracerEntry
{
  
  Property Tracer As %String

}

I want to move the Experiment property to the TracerEntry class so that there is a different Experiment allowed for each ScanSlot, like this:
